Ok well i just figured out how to use inventor to make a box design for my 12" kenwood sub, and im bored. If you want me to attempt at making a design for some speakers just post a reply with the dimensions you want the box to be, a link to the subwoofer for specs, and whatever hz you want the box to be tuned to. I'll try my best to do it right but it most likely isnt because i just figured out how to do it but oh well im bored out of my mind and i have lots of time. (winter break)
Heres a screenie of the box i made, it is tuned to 32hz (top isnt there so you can see inside, lol i don't know how to make parts transparent)
